WINDOW-SCREEN.

Liaoning ments in window screens, preferably of the f adjustable type,having a relatively Wide range of adjustment to fit windowscfdifferentwidths between the sash and top or Ybottom of the vframe forVentilating purposes, and also to exclude insects, dust and otherfloating matter.

VThernain object is to provide a screen roll mounted in one end of theframe,- and capa' ble of being extended across frames ofdifferentlengths, and attached to the opposite endthereof in such-mannerthat it may be yeasily and quickl released, and rewound upon the rollerw en desired, thus perrnittingxthe same screen to be used with rigidor'adjustable frames.

.Another object is to rovide Athe adjacent edges of the lower an upperrails of the frame Awith lengthwise f channels 'for receiving andguiding the adjacent edges of the screen, and' holding said screen in a,flat plane. 1

A further object is to provide adjustable connections between the framesections4 for holding said sections in any position'of adjustment toclosely lit between the sides of the Window frame, and at the same time,

permitting the sections to be retracted when.

removin or replacing the iframe.

A stil -further object is to construct the adjustable connections insuch manner that f Y they may be used as a `means for positivelyretracting and extending the frame sections.

Other objects and uses relating to specific parts of the screen and itssupporting trarne Will be brought out in the following description.

This screen isused. primarily for ventilating purposes, and consists ofa rectangular frame composed of lJ-shape sections 1 and 2 havingrespectively, upright parallel end bars 3 and 4-, the frame section- 1being provided with lower and upper parallel rails 5 rigidly secured atone end tothe upright bar e while vthe y section 2- isrovided with lowerand upper parallel rails f3- rigidly secured at one 'end to the uprightbar The rails 5 and 6 are spaced sub stantially uniform distances apartand. are slidably interlocked with each other to pern mit the framesections to be extended 'or retracted to fit between the upright casingsof windows of dierent widths between the sash and lower or upper portionof the Window frame, as may be desired. These'rail sections 5 and 6 arepreferably made ot' sheet metal, tubular in form, so as to fit onewithinthe other, except that their inner lengthwise edges' are providedwith substantially' fla-t flanges 7 which are spaced a slight distanceapart to,folrm relal tively narrow vertical channels 8 '`or ren ccivingand guiding the opposite lengthwise edges of a screen fabric 9 as thelatter is drawn across the frame in a manner hereina ttor described.

The main bodies of the rails 5 and arc substantially rectangular incross brought closer together at or near the .longitudinal centers ofthe main bodies to form the central lengthwise channels -8-, and at thesame time, materially stifenin the rails, it being understood that theshou ders, as -10- formed by drawing the flange portions J7- closertogether, serve-t0 lock the telescoping portionsY of the rails againstrelative lateral or vertical movement, or

rather to hold them in alinement, thereby maintaining all portions ofthe frame in a substantially flat vertical plane.

The screen +9- is preferably made of light cotton cloth or equivalentmaterial, of such dimensions as to cover the entire opening in the framewhen the latter isextended to the limit of its adjustment with itslongitudinal edges entering the channels -8- and one end attached to aroller -'-li the opposite end being secured to a light but comparativelystiff reinforcing bar -12-,' which, together with the roller -11-,serves to hold the fabric in a substantially flat plane againstbuckling, wrinkling' or folding, the bar -12- being of approximately thesame length as the verl'tical width of the fabric and is suilicientlyspring -l6- is secured, the opposite end of said spring being attachedto the roller -11-. .i

The outer end of the rod or stem -17-- is preferably angular in crosssection, as shown more vclearly in Fig. 4, and is engaged in anopen-sided slot -'-18- of a bracket 19- on the corresponding end of theupper rail v-5- so as to hold the stem against turning, the slot beingpreferably open at the top toA 'inserted therein or removed whendesired,

' and is provided near its lower end with a.

lateral enlargement forming a 'shoulder --20-- with which the angularportion of the rod or stern is'normally interlocked to preventaccidental displacement thereof,

particularly when the screen is retracted' upon the roller.

The intermediate portions of the lower andupper rails, and particularlythe inner ends of the rails -5- of the section -l-, are connected bycross bars -21- havingtheir ends rigidly secured to the adjacentportions of the rails by. any suitable fasten ing means, as tongueswhich it struck up from the opposite walls of the channels S5- and areforced into recesses -23 in opposite edges of the cross bar to firmlylock the latter against outward or. .lateralv movement relatively to theframe seclion -1-.' One of these cross bar s also constitutes aconvenient support for theop- 'erating means by which the frame sectionsmay be extended or retracted, l said operatingmeans comprising in thisinstance a cran arm -24- pivoted at one end at 25J-to one of the crossbars -21- and its other end provided with-.a handle v--26- by A clampingblock Q7- nected-to the crank arm --24- land provided with a lengthwiseopening for receiving a rod or bar -Qlfwhich is pivotally connectedat-29- to the end bar -4-, as shown'more clearly in Figs. land 2. Thisconnecting rod or bar --28* is adjustable endwise in the aperturedclamping block -27, the latter being provided with a set screw 3G- bywhich the rod maybe firmly clamped` to the block -27- to hold the framesections -3- and v lim in their relatively adjusted positions.

may be rotated about the pivot4 is pivotally .coni The crank-arm -24--and connecting rod i 28- constitute what may be termed a toggleconnection between the frame sections -l and -2-, 'and also constitute atoggle lock for lholding said sections in their extended positions, byreason of the fact that the pivotal ,connection between the crank-arm2lb-4 andv clamping member -27- assume a position in a substantiallystraight line between the pivots 25# and` 22%d with the free end of therod -28` resting on the hub ofthe 'crank-arm M24- as shown in'Iigs. 1and 2. When it is desired to contract the frame lengthwise, it is simplynecessary to swingthe crank-arm 24- upwardly to the position indicatedby dotted lines in Fig. thereby reducing the length of the frame as anentirety and permitting it to be withdrawn from the window, or in areverse manner replaced in the window. l

The lower and upper brackets -14- and l-19- at opposite ends of theroller -11- are connected by a cylindrical section -31- forming withsaid brackets and the end bar 3- of the frame a suitable housing`for andscreen wound thereon.

'The operation of my invention will now be readily understood withreference to the` foregoing description, taken in connection with thedrawings, and it is evident that all elements thereof may be substitutedby equivalents without de arting from the spirit of this invention.herefore, I do not limit myself to the precise structure show n anddescribed.

What I claim is:

1. A window screen,comprising two frame sections, slidable one upon theother, an up-` right roller housing on one end of one section, aroller.in said housing, and a screen having one end attached to theroller to wind thereon, and' its other end movable across the frame andprovided with means for attaching it to the opposite side of said frame,spring means for automatically retracting the roller to tension thescreen in j any relative position of the frame sections.

2. A Window screen, comprising a frame, having lengthwise channels inadjacent edges of opposite sides thereof, a roller housingI on one endof the frame, an upright roller j lurnaled in said housing, ascreen attached at one end to the roller, and movable across the frame and havingits opposite edges guided in said channels, the opposite end ot' thescreen being provided with means for attaching it to the correspondingend of the frame.

3. A window screen, comprising two frame sections slidable one upon theother, a cross bar connecting opposite sides of one of the sections,adjustable connections between said cross bar and the end of the othersection, and a screen stretched across the openings in both framesections."

4. A window screen, comprising two frame sections slidable endwise oneupon the other,

a roller housing on one end of one of the sections, a roller journaledin said housing, a screen attached at one end to the roller, and havingits other end provided frame sections, a crank-arm journaled on thecross bar, and connections between said crankearm and the other framesection for moving the last named section as the crankarm is rotated.

6. A window screen comprising two 'frame sections slidable endwise oneupon the other, and means for extending and retracting said sections,said means being adjustable'to varyV the degree of extension.

7. A window screen comprising frame sections adjustable endwise one uponthe other, a crank-arm journaled on one of the sections, a rod pivotedto the other section, sliding connections between the crank-arm and rod,and means for clamping the sliding connections against relative slidingmovement.

In witness whereof I have hereunto set my hand this 15 day of October1914.
